I usually transport my AI inside my van with the amas & sail on top of hull. I made up some 11/2"pvc posts to hold amas in place. They worked out well, amas stay in place, easy to load, remove, they don't bounce around when wheeling down beach to set up.

Front support bar velcros to cross member & stores in front hatch when not used. Rear support is just slipped under existing bungee and can be easily removed or rotated down when not used. I kept the centerline distance between posts same as the scupper carts posts so cart can just slip into the amas support posts while on water. Total cost less than $10.
